NEWTON BENJAMIN, OF ELMIRA, NEW YORK.

ASH-SIFTER.

Application filed February 7, 1912.

To all whom it may concern:

Be it known that I, NEWTON BENJAMIN, of Elmira, in the county of Chemungand State of New York, have invented certain new and useful Improvementsin Ash-Sifters; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in that class of ash sifterswhich are adapted to rest on the top of an ash can or other receptacle,the object being to provide means whereby the dust arising from dumpingthe ashes into the sifter and from sifting the ashes, will be confinedwithin the device.

A. further object is to provide a simple and inexpensive device,particularly adapt ed for domestic purposes, and which will be easy tooperate, and which provides for a complete separation and recovery ofthe unburned coal from the ashes.

WVith these objects in View, my invention consists in the details ofconstruction as will be more fully described and pointed out in theclaims.

In the accompanying drawings, Figure l is a view in perspective of mydevice. Fig. 2 is a view in vertical section of same. Fig. 3 is a viewin horizontal section through the part carrying the screen, the latterbeing shown in its horizontal position, and Fig. 4 is a similar viewshowing the screen in its turned position.

My device comprises two detachable sections 1 and 2 adapted to be usedwith a third section 3, which may be the ordinary ash can, barrel, orother reeeptacle'adapted to receive the ashes separated from theunburned coal. The upper section 1 consists of a cylindrical body, and atop 4, a portion 5 of which is horizontal, and the major part thereof 6inclined as shown, and provided with a circular opening surrounded by anoutwardly flaring funnel shaped rim 7 forming a hopper. Hinged to theunderside of the inclined portion 6 of the top section, is thecounterweighted door or closure 8 which latter conforms to the shape ofthe opening in the top section 1, but is of greater diameter than saidopening, so that when closed it will effectually prevent the escape ofdust from the receptacle. This door or closure 8, is provided with anarm 9 which projects upwardly over the rim 7 at the hinge sideSpecification of Letters Patent.

of the door 8, and then outwardly, and is of a weight suflicient to holdthe door up in its closed position. The lower end of the section 1 isopen and is provided above its lower edge with an externally projectingbead 10 adapted to rest on the top of section 2, when the lower end ofsection 1 is telesco-ped with the upper end of section 1. This section 2is open at its upper and lower ends and is provided at a point above itslower end with an outwardly projecting head 11 adapted to engage andrest on the upper end of section 3, which as previously explained may bean ash can, barrel or other receptacle to receive ashes. Mounted inoblong horizontal slots 12 and 13 in section 2, is the shaft 14 carryingthe screen 15. This screen is circular in shape, and conforms in size tothe internal diameter of section 2, and is centrally secured to theshaft 14, which latter has a movement lengthwise the slots so as toeffect a shaking movement of the screen, and also has a rotary movementwhereby the screen may be turned to a ver tical position in order todump any unburned coal resting thereon. In order to prevent the escapeof dust through the slots 12 and 13, the shaft 14 is provided with coverplates which latter are mounted in guides and move with the shaft, andare of suflicient length to cover the slots 12 and 18 throughout thefull shaking movement of the shaft.

Extending half way around the inner section 2, in the plane of the loweredge of the slots 12 and 13 is the shelf 17 on which the screen 15normally rests. This shelf extends from one end of one slot around tothe farther end of the other slot, so that the shelf is under one slotbut not under the other. lVhen the shaft 14 is located at the ends ofthe slots adjacent the ends of the shelf, it may be tilted to turn thescreen for dumping the unburned coal thereon, but when the shaft isshifted laterally in the slots 12 and 13, so as to project over theshelf, the latter engages the screen on both sides of the shaft, andlocks the latter against rotary or tilting movement. This shelf insteadof being continuous may be cut away at intervals, as shown, so as topermit any ashes or dust settling thereon to be removed by the shakingmovement of the screen.

The section 2 is provided with handles 18 by which it and the section 1thereon may be lifted into position onto section 3, and by which it ishandled when removed from section 1.

To operate the device the ashes are shov- I claim as new and desire tosecure by Lett ers-Patent, is

1'. As a new article of manufacture, an ash siftercomprising-areceptacle, a shelf in said receptacle and extending approximately eledor dumped onto the door 8, and as the latter is sensitive, it givesunder the weight and permits the ashes todrop onto the screen, andinstantly closes, thus confiningthe dust created or freed from theashes,- within-thereceptacle. By now moving, the shaft back. and forthin the elongated slots, the finer particles will pass through thescreeninto, receptacle 8, thus leaving, the larger ones on thescreen. By nowremovingsectionQ withsection 1, thereonfrom section 3, thelunburnedcoalon thescreen can be dumped by'simply tilting thev screen or,

if; desired the top section may be removed and the contents of the sievedumped, or.

poured out. without tilting the screen.

\Vith thisimprovement, which: is, exceed-- ingly simple in constructionand inexpen siveto make, it will beseen that ashes can be handled andthoroughly screened with out creating any dust, and, by. making, the

device in sections theparts can be conveniently and readily handledi.

Itisevident that changes in-theconstruction and relative arrangement ofthe several parts. might be made without avoiding-only invent-ion and;hence I would have itaunderstood that I' do not restrict myself" to theparticular construction and arrangement of partsshown and described,but,
